CASTEE.

Application aiedrui 14,

Rochester, in the county of Monroe and.

5 State of New York, have invented a new and Improved Caster, of which the following is a specification.

My invention relates to infants beds of the knock down or folding type and more particularlyto a caster for a bed of such character, an object of the invention being to provide a caster or supporting wheel adapted, when in inoperativeposition, to lie within and parallel to the base of the bed.

The accompanying drawings illustrating my invention are as follows:

Figure 1 is a side elevation of a folding bed, a portion of the side thereof toward the observer being brolrenaway, Fig. 2, an end view as seen from the right of Fig. 1; Fig. 3, an enlarged. end view showing the bed in its folded or knocked down condition; Fig. 41, a plan view from the under sidewith the sides and ends opened .out but with the supporting wheels swung to inoperative position, a portion only of the springs and mattress being shown; Figs. 5 and 6, enlarged. top plan View and elevation, respectively, of a corner of the base member showing details of construction to be explained; and.

Fig. 7-, a vertical sectional view taken along the line 1-1 of Fig. 1 but showing the hinged upper side section in its lowered position. I a

Similar reference characters refer to similar parts throughout the several views.

The bed comprises a rectangular base or body portion 1 for containing the springs 2 and mattress 3 and having side and end walls. To such side walls there are connected by hinges d the front and rear side frame members 5 and 6, respectively, while to the end walls are similarly connected the end frame members 7, all of such members having perforated panels therein, preferably of wire screen, which provide for plenty of ventilation. These sides and ends are adapted to fold inwardly and when closed to occupy the relative positions in 50 whichthey are seen in Fig. 3, the end members 7 being on the bottom andagainst the mattress 3, then the side member 5 and with the other side member 6upon the top.

When the bed is open and ready for oc- 5a cupancy the sides 5 and 6 overlap the ends 7 to be dropped to folded position.

and all four members are'securely held in upright position by latches 8, which are pivotally connected to plates 9 secured to the sides and near the tops of the end frame members 7 and slotted at their outer ends to engage over studs 10 carried by plates 11 secured on the end edges of the. side frame, members.

In order that a child may more easily be such sections "being held by latches 8, as

above described, to theend members independently oi? each other so that the top section 12 when released may-be swung outwardly and dropped to the position in which it isseen in Fig. 7; v Secured to'the bottom of the base 1 are plates 19 extending diagonally across the corners thereof and these plates have. up-v wardly extending reinforcing members 20 secured by screws to the inner faces of the side andend Wallsof the base. Uponthe plates 19 there is supportedan angle iron frame 21 comprising the supporting means for the springs 2 which are of the flat inter woven wire type, as'indicated in Figs. land 7, and connected to the said frame by links 22. The mattress 3 rests upon the springs 2 and the top thereof comessubstantially in line with the lower edges of the end frame members 7 thus permitting such members The supporting wheels or casters 23 are of comparatively large diameter it is preferable that the mattress be supported several inches above the floor, and itislone of they main objects of my invention to so pivotally connect these wheelsto the base 1 in a way that when the sides and ends are folded the wheels, also, can be folded. that is,swung to occupy a position fiat against the springs 2, as seen in Fig. 4t, thereby permitting the bed being more easily carried from'place to place and causing it to occupy considerably less space in transportation and in storage than it otherwise would. Each of the plates 19 has a centrally disposed slot 241. eXtending inwardly t'rom one edge for receiving" the shank of a T-bolt 25 the head of which is pivoted in bearings 31' formed on the upper face. of the plate and adjacent the sides of such slot. These bolts respective slots 24: and to be looked when GX- tending outwardly and through the slots, as in Fig. 6, by latches 26 pivoted at one end to the projections 27 extending rearwardly' from the plates 19 and slottedv near their;

pivoted latch movable across the race of centers to engage the bolts, such latches be: ing disposed between the bottom of the plates 19 and shoulders 28 formed on the bolts. Loosely mounted on the bolts below the shouldered portions 28 are the heads 29 of forks 30 between the outer ends oiiwhich areniounted the supportingwheels In Figsni and (Sithe bolt 2-5 is shown inits unlocked and looked positions, respectively, the wheel and forks being removed; ltwill be seen that, when the latches 26 are released and the bed tipped upon its side, the

boltscan be swung substantially ninety degrees in planes at right anglesto the bottom of the base 1, and that with the heads 29 freely revoluble on the bolts the' \vl1'eels can be turned tolie fiat against the springs, asin Fig. 4;.

What I claim is: p I I. In combination with a basefa slotted supporting plate on the under side of the base, a bolt normally CXtGIlCllllg through W said slot and pivoted on the plate to swing inwardly to an inoperatlve position parallel withthe bottom ofthe base,"a swivel wheel inountedon said bolt, and a pivoted latch movable acrosst-he face of said plate to hold the bolt inoperative position. s

In combination with abase, a slotted supporting platoon the under side of the base, a T-bolt normally extending throngh said slot and pivoted on the plate to swing inwardly to an lnoperative position parallel r 1 with the bottom oi: the base, a swivel wheel mounted on said bolt, and means for holding; said bolt in operative position comprising a "said bolt, a swivel wheel mounted on said bolt, and means for holdingsaid bolt in on erative position comprising;- a pivoted latch movable across thei'aee of said plate, engaging between the plate and the said shoulder and having a notch for receiving the bolt.

l. In combination with a base, a slotted supporting plate on the under side oi: the base, reini o eing members extending upwardly from the plate and. secured to the base a T-bolt normally extending through said slot and pivoted on the plate to swine inwardly to an inoperative position parallel with the bottom of the base, a shoulder on said bolt, a swivel wheel mounted on said bolt, and means for holding said bolt operative position con'iprising a latch pivoted to the plate and movable across the face thereof, such latch engaging between the plate and [said shoulder, and having a notch for receiving the bolt.
